Getting reliable test results

Spare tubes are useful when one breaks, when glass becomes stained by reagents over time, or when you want to run several tests side by side. Fill each tube exactly to the 5 ml line with water from the tank, as most API liquid tests are measured against that volume, and read the colour against the card in daylight or under white light. Using a separate tube for each parameter, with a small label on the cap, avoids carry-over between tests. Keep the cap pressed on firmly for tests that call for vigorous shaking, rinse tubes with clean water afterwards rather than soap, and let them dry upside down. They suit both aquarium and pond kits.

Good to know

Rinse tubes with clean water after each test so results are not affected by leftover reagent.
